LUBRICATINVGDEVIICE FOR E CCENTRICS.

SPECIFICATIONforming part of Letters Patent No. 611,854, dated October 4, 1898. Application led January 8,1898. Serial No. 666,027. (No model.)

To all whom t ntay concern,.-

Be it' known that I, FREDERICK OssIAN BALL, a citizen of the United States, residing at Plainfield, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Lubricating Devices for Eccentrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lubricating devices for eccentrics; and it consists in certain improvements in the construction thereof, as will be hereinafter described, and pointed out in the claims.- l

More particularly, my invention relates to the eccentric mechanism of automatic cut-off engines and the means for supplying oil to said mechanism. A

The invention is illustrated in the accompanying drawings, as follows:

Figure l shows a View of the eccentric mechanism,partly in elevation and partly in section. Fig. 2 is a section on the line 2 2 in Eig. 1. V"

A marks the shaft upon which the eccentric mechanism is mounted, usually the crankshaft of an engine; B, a frame secured to the shaft; C, the pin on which the eccentric is pivoted, said pin having the extension C' prof jecting through a portion of the frame B; C2, a nut on the extension C for securing it in place; D, the eccentric, and E the eccentricstrap. The eccentric is provided with the usual slot around the shaft A, so that it is free to swing on the pivot formed on thepin C. A governor or other device (not shown) is usually provided for controlling the swing of the eccentric on the pivot-pin C, and as the throw of the eccentric is changed by a change of position of the eccentric on its pivot l the throw of the eccentric is thus controlled.

The eccentric-pin C has a longitudinal duct c and radial ducts c', leading from the duct c to the surface of the pin. A brass bushing D is placed in the eccentric, and a circumferential groove c2 either in the bushing or the eccentrichpin (shown in the pin) connects the several ducts c with the ducts drin the bushing. A longitudinal groove c3 facilitates the distribution of oil for the bearing on the pin C. A circumferential groove d either in the bushing or eccentric (shown in the bushing) connects the several ducts el with the duct cl2, which leads to the eccentric-bearing.

An oil-receptacle F of annular form encircles the shaft and is secured by screws f to the pin C. The cavityF of the receptacle is somewhat eccentric to the shaft, and at the point the most remote from the axis a duct f connects the cavity with the duct c.

The outer flange of the receptacle is far enough from the shaft to allow the introduction of the tube g, leading from the oil-cup G.

In operation the oil is dropped into the receptacle and is carried by centrifugal force into and through the ducts f c c to the pivotbearing, which is thus lubricated, and thence by the groove c2, duct d, groove d', and duct Z2 to the eccentric-bearing. Of course it will be understood that if the outwardly-extending duct c is in register with outward duct d very little, if any, oil will flow circumferentially in the groove c2, and if care is taken to get the bushing D so positioned in the eccentric as to bring the duct d into register with the duct cl2 the groove CZ may be dispensed with. I prefer, however, the construction having the circumferential grooves, as the assembling of parts are thus much simplified.

What I claim as new is- K 1. In a lubricating device for eccentrics, the combination with the eccentric-shaft and a frame secured to said shaft; of a pin secured to said frame; an eccentric pivoted on said pin; a strap on said eccentric; and an oiling mechanism arranged to conduct oil t0 the pivot-bearing and from the pivot-pin to the eccentric-bearing.

2. In a lubricating device for eccentrics, the combination with the eccentric-shaft; and a frame secured tol said shaft; of a pin secured to said frame; an eccentric pivoted on said pin; and an annular oil-receptacle secured to said pin and encircling the shaft, said receptacle and pin being provided with ducts leading from the receptacle to the pivotbearing.

3. In a lubricating device for eccentries, the combination with the eccentric-shaft; and a frame secured to said shaft; of a pin secured to said frame; an eccentric pivoted on said pin; a strap on said eccentric; and an IOO annular oil-receptacle secured to said pin and having the duct, cl2, said eccentric and pin encircling the shaft, said receptacle, pin and having a circumferential groove connecting eccentric being provided with ducts connectducts, c and d2, a strap on said eccentric; ing the receptacle with the pivot-bearing and and means of supplying oil to the duct, c.

5 the pivot-bearing with the eccentric-bearing. In testimony whereof I affix my signature I5 4r.
